      Without RTTI TypeIndex library will switch from using <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">typeindex</span><span class="special">::</span><span class="identifier">stl_type_index</span></code>
      class to <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">typeindex</span><span class="special">::</span><span class="identifier">ctti_type_index</span></code>. <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">typeindex</span><span class="special">::</span><span class="identifier">ctti_type_index</span></code>
      uses macro for getting full text representation of function name for each type
      that is passed to <code class="computeroutput"><span class="identifier">type_id</span><span class="special">()</span></code>
      and <code class="computeroutput"><span class="identifier">type_id_with_cvr</span><span class="special">()</span></code>
      functions.
    </p>
<p>
      This leads to big strings in binary file:
    </p>
<pre class="programlisting"><span class="keyword">static</span> <span class="keyword">const</span> <span class="keyword">char</span><span class="special">*</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">detail</span><span class="special">::</span><span class="identifier">ctti</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;::</span><span class="identifier">n</span><span class="special">()</span> <span class="special">[</span><span class="identifier">with</span> <span class="identifier">T</span> <span class="special">=</span> <span class="keyword">int</span><span class="special">]</span>
<span class="keyword">static</span> <span class="keyword">const</span> <span class="keyword">char</span><span class="special">*</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">detail</span><span class="special">::</span><span class="identifier">ctti</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;::</span><span class="identifier">n</span><span class="special">()</span> <span class="special">[</span><span class="identifier">with</span> <span class="identifier">T</span> <span class="special">=</span> <span class="identifier">user_defined_type</span><span class="special">]</span>
</pre>
<p>
      While using RTTI, you'll get the following (more compact) string in binary
      file:
    </p>
<pre class="programlisting"><span class="identifier">i</span>
<span class="number">17u</span><span class="identifier">ser_defined_type</span>
</pre>
